For some time now the forum had problems with the registration process. The settings are adjusted now and registration should work again. I am sorry for all the trouble anybody had. Those that were not able to register in the past, please try one more time and register a new user account. You may have to register a new user because the older inactive user accounts have been removed. New user accounts created within 2017 have been activated manually (without sending registration mails).

Please do not forget to write a short introduction here - viewforum.php?f=62 - it will let us know that you are not a spam user.
